On the one hand, shown in Figure 10 (c), the formation cross section roughly is circular-arc stria 26 below the arm 5a of slide block 5, this stria 26 from end side thereafter towards central portion and the outside, downside, rear openings, accommodate the part of above-mentioned volute spring 14 in this stria 26, the anterior end surface 26a of stria 26 becomes the face of the elastic repulsion power of bearing volute spring 14.Below arm 5a, form groove 27 along fore-and-aft direction, these both sides, groove 27 front and back, open lower side, the projecting strip part 13 of base shell 1 is snapped into wherein.
Promptly, when the assembling of memory card socket is finished, the moving direction of slide block 5 is limited by the principal plane of principal plane, the lateral plate 6a of base shell 1,2 projecting strip parts 13 and cover housing 2, and the supporting pieces 12 by base shell 1 limits with the leading section butt of arm 5a and forwards continues to move.Slide block 5 is by volute spring 14 application of force forwards, so storage card MC is when inserting socket main body 3, and slide block 5 may slide between the position that socket main body 3 takes off in the I/O of storage card MC surface of contact and contact 10 position contacting and storage card MC.
The removable heart-shaped cam slot part 15 that snaps in freely of axial region 16a of formation cam pin 16 on the front part of the arm 5a of slide block 5, the rear side of heart-shaped cam groove 15 form and are arranged on the groove 25 that the lock body 24 on the cover housing 2 is inserted into.As Figure 10 (a) with (d), heart-shaped cam groove 15 is made of heart-shaped cam 15a, the gathering sill 15b that forms in heart-shaped cam 15a perimembranous.When the axial region 16a of cam pin 16 was snapped in gathering sill 15b, along with moving forward and backward of slide block 5, axial region 16a the relatively moving in gathering sill 15b of cam pin 16 was by in the formed male and fomale(M﹠F) 15c channeling conduct of the bottom surface of gathering sill 15b and gathering sill 15b.
On the front part of the arm 5a of slide block 5, and, form the recess 15d that opens to the front side in the front portion of heart-shaped cam 15a.Slide block 5 moves to after the rearmost position, when the power that pushes storage card MC is disengaged, because the axial region 16a of cam pin 16 embeds in the recess 15d, and slide block 5 mobile being limited forwards, slide block 5 rests on the assigned position.
Its right end face of the groove 25 that is provided with on the arm 5a of slide block 5 forms to the outstanding extension 29 of the interior side direction of socket main body 3 at front side portion.When slide block 5 moves to the afore mentioned rules position, shown in Figure 24 (a), the bar sheet 24a of extension 29 urge lock bodies 24, lock body 24 elastic deformations, make the top (snap-latch piece 24b) of lock body 24 enter storage card MC locking with in the recess 101, MC locks to storage card.On the other hand, shown in Figure 24 (b), when storage card MC is not installed, move at slide block 5 under the state of extracting position of storage card MC, extension 29 leaves from lock body 24, and the power of lock body 24 bendings is disappeared, and therefore utilizes the elastic restoring force of lock body 24, the top ends of snap-latch piece 24b retreats with recess 101 and keeps out of the way in the groove 25 (getting back to the initial period position) from locking, and releasing is to the locking of storage card MC.
In addition, groove 25 is positioned at the upside of mosaic process 39, and the lock body 24 that therefore is configured in the groove 25 engages with the upper portion of locking with recess 101, and mosaic process 39 engages with the lower portion of locking with recess 101.
When assembling this memory card socket, at first being pressed into of rear portion that each contact 10... is pressed into the matrix 7 that is opened on contact block 4 used the hole, and from the top common terminal daughter board 30 and travelling contact plate (switch plate) 31,32 be pressed into be fixed to matrix 7 be pressed in the groove 33 assembling contact block 4.Afterwards, the matrix 7 of this contact block 4 is placed on the base shell 1, the protrusion tab 9 of base shell 1 is pressed into following being pressed in the groove 8 that is opened on matrix 7, thus matrix 7 is fixed on the base shell 1.At this moment, the leading section of the arm 7b of matrix 7 engages with the snap-latch piece 1a of base shell 1, the offset of the leading section of restriction arm 7b.
Then, be inserted in a distolateral maintenance that makes volute spring 14 under the state of spring suppport 7c of matrix 7, for another distolateral being inserted in the stria 26, and the projecting strip part 13 of base shell 1 is embedded in the groove 27, slide block 5 is placed on the base shell 1 volute spring 14.Then, one of cam pin 16 distolateral axial region 16b is snapped in the connecting hole 12a on the supporting pieces 12 that is arranged on base shell, and another distolateral axial region 16a of cam pin 16 is snapped in the heart-shaped cam groove 15 of slide block 5.Afterwards, under the state in the mosaic process 7e that makes matrix 7 is fitted to the embedded hole 2b of cover housing 2, the form of cover housing 2 with frame is placed between the top ends of two lateral plate 6a, 6b of base shell 1, utilizes laser bonding that the junction of base shell 1 and cover housing 2 (cover housing 2 about the docking section of lateral margin and the top ends of two lateral plate 6a, the 6b of base shell 1) engaged.Thus, the case shape socket main body 3 that the front forms plug-in card inlet 3a is formed, and (with reference to Fig. 1 (a) and Fig. 3 (a)) finished in the assembling of memory card socket.
At this, when assembling cover housing 3, (plug-in card inlet 3a side) promotes slide block 5 by forwards owing to the application of force of volute spring 14, and the leading section of the arm 5a of slide block 5 docks with the supporting pieces 12 of base shell 1, and restriction slide block 5 forwards continues mobile.Under this state, the extension 29 that is arranged on the slide block 5 is configured in the position of leaving from the lock body 24 that is arranged on the cover housing 2, therefore there is no need lock body 24 to be applied tension force on one side, assemble cover housing 2 on one side, having the lock body 24 of raising is the such effect of operation of the assembling operation of cover housing 3.In addition, under this state, an end of cam pin 16 moves to the position A (with reference to Figure 10 (a)) of the rear end of gathering sill 15b.
In addition, on the supporting pieces 12 that the cephalolateral margin bending by base shell 1 forms, be equipped with to the outstanding narrow projection 12b of width in side, make the downward stage portion of the bonding pad 2a of cover housing 2 dock (with reference to Fig. 1 (b)) with this projection 12b, utilize laser bonding and engage.Thus, supporting pieces 12 is connected with cover housing 2, therefore can improve the intensity of supporting pieces 12.Therefore, along with slide block 5 moving of direction forwards, backwards, the axial region 16a of cam pin 16 heart-shaped cam groove 15 in mobile when, can make the action of axial region 16a stable, its result, the front and back action of slide block 5, the Plug Action that is storage card MC is stable, can improve the number of times of anti-plug of storage card MC.As Figure 12 (a) with (b), the compressing tablet 22 that utilization forms by a part of cutting, holding up shell 2, one of cam pin 16 distolateral axial region 16b is pressed in supporting pieces 12 sides, therefore can prevent that the distolateral axial region 16b of cam pin 16 from coming off from the axis hole 12a that is arranged on the supporting pieces 12.
In the assembled state of this memory card socket, (plug-in card inlet 3a side) promotes slide block 5 by forwards owing to the application of force of volute spring 14, and the leading section of arm 5a docks with the supporting pieces 12 of base shell 1, and slide block 5 is constrained to and can not forwards continues to move thus.Under this state, an end of cam pin 16 moves to the position A (with reference to Figure 10 (a)) of the rear end of gathering sill 15b.
At this, on left and right directions (Width), corresponding between the arm 7b of the supporting pieces 12 of base shell 1 and the matrix 7 of contact block 4 with plug-in card inlet 3a.The stage portion 7d of the arm 7b of the stage portion 5d of the arm 5a of slide block 5 and the matrix 7 of contact block 4 sets the greatest width dimension of the both sides that are a bit larger tham storage card MC for more by the size between the medial margin of upside.The back side (the formed face of I/O surface of contact) that makes storage card MC is top relative with the base plate 1c's of base shell 1, suppose from plug-in card inlet 3a and insert storage card MC, the stage portion 7d of the arm 7b of the stage portion 5d of the arm 5a of slide block 5 and the matrix 7 of contact block 4 is more by the size between the medial margin of below, set for be a bit larger tham be formed on the total length of fore-and-aft direction along the both side edges at the back side of storage card MC downward stage portion 103 (with reference to Fig. 1 (a), Fig. 4 and Fig. 5) more by the size of the both sides width of below.Also have, on above-below direction (thickness direction), the height dimension between top and these stage portion 5d, the 7d of the base plate 1c of base shell 1 top is set the downward height dimension of the downward stage portion 103 that is slightly smaller than storage card MC for.
Adopt this structure, in the rear side of storage card MC under the state of the upper face side of the base plate 1c of base shell 1, storage card MC can be inserted from the plug-in card 3a that enters the mouth in the top of the stage portion 7d of the arm 7b of the stage portion 5d of arm 5a that the downward stage portion 103 of storage card MC can be by slide block 5 and the matrix 7 of contact block 4.On the contrary, when making storage card MC surface (with the face of a formed opposite side of I/O surface of contact) above the base plate 1c of base shell 1, between the medial margin of the stage portion 7d of the arm 7b of the stage portion 5d of arm 5a that the breadth extreme of storage card MC part can not be by slide block 5 and the matrix 7 of contact block 4, can prevent that mistake by the positive back side direction of storage card MC from causing misplug into.
Shown in Fig. 7 (b), on the base plate 1c of base shell 1, and, form catch 11a by cutting, holding up corresponding to the medial margin of the front side (plug-in card inlet 3a side) of the hole 11b of the set right-hand member of the contact 10b (with reference to Fig. 9 (a)) of the right-hand member of contact block 4.Storage card MC with standard when inserting plug-in card inlet 3a along fore-and-aft direction, for each contact 10 is incorporated into the I/O surface of contact, the groove (not shown) at the back side by being set at storage card MC, each contact 10 can relatively move to contact position with respect to storage card MC.Relative with it, when wanting fore-and-aft direction oppositely to insert storage card MC, catch 11a meets in the front face branch of the direction of insertion of storage card MC, and storage card MC continues mobile being limited.Its result, the front of the inserting side of storage card MC can not run in the top of each contact 10, can prevent owing to contact the distortion at the top of each contact 10 that is caused with the front of the inserting side of storage card MC.
Next, the action to plug storage card MC in the memory card socket of present embodiment describes.When storage card MC is not installed, be subjected to the elastic repulsion power of volute spring 14, slide block 5 forwards moves, and stops with the position that the supporting pieces 12 of base shell 1 docks up to the leading section of the arm 5a of slide block 5.Under this state, the snap-latch piece 24b of lock body 24 keeps out of the way in the groove 25, and the top ends of snap-latch piece 24b can be more not outstanding than the medial surface of arm 5a.
Under this state, with the fore-and-aft direction of storage card MC and positive back side direction with standard in the plug-in card inlet 3a that inserts socket main body 3 time, storage card MC enters between the arm 7b of matrix 7 of the arm 5a of slide block 5 and contact block 4, stage portion 5d that downward stage portion 103 mountings of the following both sides of storage card MC are provided with to the arm 7b of the matrix 7 of the arm 5a of slide block 5 and contact block 4 and the top of 7d.When further inserting storage card MC in the socket main body 3, the inclination excision portion that the right side was provided with 102 of the leading section of storage card MC and the abutting part 5c butt of slide block 5, rearward sliding piece 5 (with reference to Figure 13 (a)).In addition, under this state, do not load on the cam pin 16.
Then, if overcome the elastic repulsion power of the volute spring 14 that is applied on the slide block 5, further push storage card MC to the inside, along with moving of storage card MC, slide block 5 retreats.Because retreating of slide block 5, the axial region 16a of cam pin 16 is guided by the male and fomale(M﹠F) 15c of the bottom of the gathering sill 15b of heart-shaped cam groove 15 on one side, in gathering sill 15b, move on one side, move among Figure 10 (a) position B (in fact, because slide block 5 rearward moves, on one side the axial region 16a broad ways of cam pin 16 is shaken, on one side gathering sill 15b rearward move).Then, when the close position of position of front of base portion 7a of matrix 7 of contact block 4 is run in the back that storage card MC is pressed into the teat 5b of slide block 5, the axial region 16a of cam pin 16 arrives the position C of the leading section of meeting gathering sill 15b, can not continue to be pressed into storage card MC.At this moment, along with move at the rear of slide block 5, be arranged on the extension 29 on the inner side end of groove 25 of arm 5a of slide block 5, bar sheet 24a butt with the lock body 24 of cover housing 2, make the interior side direction bending of bar sheet 24a to socket main body 3, therefore direction is outstanding more to the inside than the medial surface of the arm 5a of slide block 5 for the snap-latch piece 24b of lock body 24, and the locking that snaps in storage card MC is with recess 101.Thus, storage card MC is locked, can prevent that storage card MC from coming off.
When this location solution removes the push-on force that is applied on the storage card MC, be subjected to the elastic repulsion power of volute spring 14, slide block 5 is got back to the place ahead with storage card MC.At this moment, on one side the axial region 16a of cam pin 16 is directed to groove 15b guiding, Yi Bian move to the position D in the recess 15d that embeds heart-shaped cam 15a.Therefore, by the axial region 16a of cam pin 16 and the recess 15d butt of heart-shaped cam 15a, mobile being limited that slide block 5 continues forwards, the storage card MC of locked body 24 lockings is also with this stationkeeping (with reference to Figure 13 (b)) in socket main body 3.At this moment, the elastic load of volute spring 14 is added on the supporting pieces 12 through cam pin 16, yet by as described above with supporting pieces 12 and the bonding pad 2a solder joints that is arranged on the cover housing 2, reinforce supporting pieces 12, even therefore apply the elastic load of volute spring 14, supporting pieces 12 is also indeformable, and cam pin 16 is stably moved.
Storage card MC is owing to being pressed into when moving to assigned position, forwards contacts formed each self-corresponding I/O surface of contact in the back side of storage card MC successively in the top of each outstanding contact 10... from the base portion 7a of the matrix 7 of contact block 4.The top ends that is stored card MC from the outstanding to the inside travelling contact plate (switch plate) 31 of medial surface of the arm 7b of the matrix 7 of contact block 4 pushes, contact (installation and measuring contact just) conducting between travelling contact plate (switch plate) 31 and the common terminal daughter board 30 with shared terminal strip 30.By utilizing this switching signal, can be according to the testing circuit (not shown) of outside, the situation that storage card MC is inserted into normal place detects.
With the side of travelling contact plate (switch plate) 32 corresponding storage card MC on; be provided with the recess 105 of the handgrip 104 that exposes write protection switch 100; according to the position of the handgrip 104 that is positioned at recess 105, the top of travelling contact plate (switch plate) 32 rests on the handgrip 104 or falls in the recess 105.Corresponding therewith; between travelling contact plate (switch plate) 32 and the common terminal daughter board 30 (promptly; the position probing contact of write protection switch 100) switches on or off; therefore utilize this switching signal; can whether storage card MC be in write protect state detect according to the testing circuit (not shown) of outside.
In addition, in the present embodiment, as shown in figure 20, be arranged on fixed contact 41a, the 41b of the convex on the fixed contact plate 41,42 and contact, therefore can improve contact stabilization with 2 of V-shaped groove 31c, 32c on being arranged on the 31b of contact spring portion, 32b.Therefore the formed position of V-shaped groove 31c, 32c among the 31b of contact spring portion, the 32b tilts sideling with respect to the plug direction of card, can increase the displacement of V-shaped groove 31c and the formed position of 32c when blocking insertion, can improve the effect of rubbing contact.Also have; in the standard of storage card MC; the dimensional tolerence of Width is less than the dimensional tolerence of thickness direction; the 31b of contact spring portion, the 32b of travelling contact plate 31,32 is along the Width and card surface or write protection switch butt of storage card MC; therefore than along size difference big thickness direction and the situation of blocking surface or write protection switch butt, more can improve contact stabilization.
In order from socket, to take out storage card MC, at first push the rear portion of exposing outside storage card MC from the plug-in card inlet 3a of socket main body 3 along direction of insertion, slide block 5 is moved to direction of insertion with storage card MC.Utilizing should be mobile, and the axial region 16a of cam pin 16 breaks away from from the recess 15d of heart-shaped cam 15a, and was directed to groove 15b guiding and comes out to the place ahead, right side from recess 15d, moved to the position E in the gathering sill 15b.
Afterwards, remove when pushing the power of storage card MC, slide block 5 utilizes the elastic repulsion power of volute spring 14 forwards to move.When slide block 5 is forwards mobile,,,, move to the position A of the rearward end of gathering sill 15b Yi Bian pass through the interior position F of gathering sill 15b on the right side of heart-shaped cam 15a on one side the axial region 16a of cam pin 16 is directed to groove 15b guiding along with moving of slide block 5.
Along with slide block 5 moving forwards, the extension 29 of slide block 5 leaves the bar sheet 24a of the lock body 24 of cover housing 2, so the power of bent stick sheet 24a disappears, and bar sheet 24a gets back to initial position, and the top ends of snap-latch piece 24b is kept out of the way in the groove 25 of arm 5a.Therefore, snap-latch piece 24b and locking are disengaged with the fastening state of recess 101, and the locking of storage card MC is disengaged.Expose much from the plug-in card inlet 3a outside of socket main body 3 at the rear portion of storage card MC, therefore may take out storage card MC from socket main body 3.
